618.0. "Ingres embedded SQL application -> Rdb?" by GLORY::LAI (Chak Lai @FAC, (313)553-5502 DTN456) Wed Apr 11 1990 21:40

    I would like to find out how feasible (i.e. easy) it is to convert an
    existing Ingres application using embedded SQL to Rdb.

    Does anyone have any idea about the effort required?

    Cheers,

    Chak Lai

	You're going to have to determine how Ingres SQL maps to Rdb SQL which I don't have a clue. Also, you should check (or at least ask) to be sure the application is not using QUEL ? Finally, Ingres has lots of extensions to SQL such as string manipulation, concat., and other functions (such date arith), so don't forget to look through these items. -- gerry
